Semantic Query on Annotated Web Pages

One important reason of doing semantic annotation is creating formally annotated documents so that machines can perform standard queries to manipulate data. However, these standard query languages, such as XQuery, are still too hard to ordinary web users, who are going to write nothing harder than natural language questions. Therefore, it is very interesting to ask how we can convert natural language questions to machine-processable queries; and this is the intuition of the project. This is a project that I am participating now. There are also some other research projects in which I have involved or am involving.
